      Coral culture and transplantation and restocking of giant clams in the Philippines 

      ED Gomez, PC Cabaitan & KC Vicentuan - In JH Primavera, ET Quinitio & MR Eguia (Eds.), Proceedings of the Regional Technical Consultation on Stock Enhancement for Threatened Species of International Concern, Iloilo City, Philippines, 13-15 July 2005, 2006 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Recently, the Pew Project (2001 to 2005) of the senior author entitled ‘Coral reef habitat and productivity enhancement through coral transplantation and giant clam restocking’ was implemented with the aim to improve the biodiversity and productivity of stressed coral reef habitats in 10 selected demonstration sites in the Philippines. These were meant to serve as models for other communities. Transplantation of corals and reseeding of giant clams were the approaches. Nubbins or small fragments from nearby large coral colonies and abundant solitary forms were transplanted to the target sites. Care was exercised to avoid or reduce any negative impacts on the natural source communities. Only cultured giant clams were used, specifically the threatened Tridacna gigas at sizes that would ensure their chances of survival in the wild (approximately 20-30 cm shell length). Following deployment, monitoring activities were undertaken, focusing on macro-invertebrates and fish, as well as the assessment of the survival and growth of experimental animals. Liaison work was done with local communities to raise their environmental awareness and to ensure their cooperation. This manuscript draws principally from results of the Pew Project. At present, two other restoration projects supported by the European Union and the Global Environment Facility Coral Reef Targeted Research Project are being implemented at the Bolinao Marine Laboratory of the University of the Philippines Marine Science Institute (UP-MSI) in Pangasinan. These projects are testing the efficiency of floating and standing coral nurseries in growing coral nubbins in addition to transplanting fragments or branches of corals to restore degraded coral reefs.

      Giant clam hatchery, ocean nursery and stock enhancement 

      SS Mingoa-Licuanan & ED Gomez - 2007 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Aquaculture extension manual; No. 37
      This manual is meant to serve as a guide to the culture of giant clams (Bivalvia, Subfamily Tridacninae). The first part focuses on hatchery methods. The second part is about the ocean nursery. The first two sections refer to selection and setting the ocean nursery site. Clam transport is introduced next although this is further tackled in the last part of this manual. Finally, the third and last part discusses the purposes of stock enhancement, survey methods for stock assessment, transport, monitoring and record keeping.
